IMPROVEMENT IN VELOCIPEDES.

Specification forming part of Letters Patent No. 140,290, dated June 24, 1873; application filed November 27, 1872.

To all whom it may concern:

Be it known that I, LEWIS T. MCGILVRAY, of Staunton, in the county of Augusta and State of Virginia, have invented a Geared Handflarriage, of which the following is a specification:

The invention consists in combining with a vehicle, having ordinary sustaining-wheels and a guide-wheel in front, a series of crankshafts and intermediate gear-wheels, by which power is easily and conveniently transferred from the hand to the axle.

Figure l is a sectional elevation, showing one form of my invention, and Fig. 2 is a side view of a modification.

A A in the drawing represent a pair of large wheels, having an axle, a, on which is supported the seat-frame B. U U are two hand-levers, (only one shown in Fig 1,) which are pivoted to the sides of frame B. c c are straps that connect the levers to the crank arms at 61, arranged at an angle to one another 'on shaft D. On shaft D is also a pinion, d,

that drives the series of wheels of g h i. The latter turns a shaft, K, having crank-arms k is placed at an angle to each other, and connected by straps k 70 to the arms l l, which are also placed at a corresponding angle to each other on the axle L. M is the guide wheel, placed in a frame, N, swiveled so as to be turned by foot-pressure on either side of plate 0.

The operation is as follows: The person sitting in the carriage works the hand-levers (J (J in opposite directions with his hands, while he steers with his feet against the plate 0. The power is transmitted through the gear-wheels to the crank-shaft K that rotates through its connections the axle L. Both wheels A A may be fast to the axle, or one may he loose. The carriage may be open or inclosed in a case representing a horse or other animal.

In Fig. 2 is showna modification of my invention as applied to another form. Z represents the figure of a man; Y, a horse; X X, the propelling-levers; X X, the straps which connect them to the operative mechanism placed within. W V are the hind legs, V V
